Hello, I am installing OBM 8.9 Decision Server Rules on Windows 2012R2 as a development server. I've followed the steps to install and configure using WebSphere Liberty and embedded Derby database, but when I start the server and view in a browser, I see this exception. Does anyone know the reason? I've tried adding feature jsf-2.2 to the Libery server.xml file, but see same exception:

Thanks for the reply - I've stopped the server, removed the jsf 2.2 line, and then started the server again, and reloaded the page - and received the same error.

For what it is worth, I installed ODM 8.9 on a second server using a different stack: Ubuntu linux (instead of Windows) and IBM JRE 8 (instead of Oracle JRE 8), and I see the identical NoClassDefFoundError (and never added the jsf-2.2 feature to server.xml). So I'm suspecting I missed a step or made the same mistake on the installation of both servers, but I'm not sure yet what I might've done wrong.
